Hollywood’s A-listers had a spring awakening this week, with actresses stepping out in colorful, floral numbers despite sub-zero temperatures plaguing several parts of the country. But while Uzo Aduba and Kate Hudson come up roses, Pink’s bouquet-covered frock just doesn’t bloom.

Uzo Aduba

The “Orange Is the New Black” star cleans up nicely once again, donning a colorful L.K.Bennett sheath dress at the annual Essence Black Women in Hollywood luncheon at the Beverly Wilshire Hotel in Beverly Hills.

Kate Hudson

Yellow was popular on the runways at NYFW, and Hudson proves that the color can be worn successfully in a Michael Kors floral skirt and coordinating crop top at the designer’s fashion show at Spring Studios.

Camilla Belle

The 28-eight-year-old actress amps up the glam factor at the Bulgari and Save the Children STOP. THINK. GIVE. pre-Oscar event at Spago in Beverly Hills in a sequined Naeem Khan frock.

Rihanna

The fashionable singer proves that even bad girls can clean up real good as she sports a form-fitting Zac Posen dress at the designer’s show at Grand Central Station.

Pink

The pop-rock singer ditches her traditional rocker-chic look and, for some unknown reason, settles on this floral schoolmarm frock from Michael Kors at the unite4:humanity gala in LA.

Michelle Monaghan

The “True Detective” actress unfortunately channels her inner-Vampira in this gothic black and lace Dolce & Gabbana frock at the Costume Designers Guild Awards at the Beverly Hilton hotel in Beverly Hills.

Rooney Mara

It’s not often that a celeb agrees to wear a dress that makes them look noticeably wider. This odd tunic — with waistline cutouts over wide-legged pants — manages to accomplish just that on the “The Girl with the Dragon Tattoo” actress at the Vanity Fair, Barneys New York and Oxfam dinner in LA.

Rita Ora

It’s hard to believe it’s even Rita underneath the layers of fur and slicked-back hair, but somehow the 24-year-old actress manages to appear twice her age wearing a Tommy Hilfiger ensemble at the designer’s show in NYC.

Knightley’s pilgrim-inspired Burberry frock at the Writers Guild Awards LA ceremony is a dull look from the “Imitation Game” actress, but she returned to form days later in a fun, colorful Alexander Lewis dress for her appearance with co-star Benedict Cumberbatch on “The Ellen DeGeneres Show.”
